These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Specific Embodiments

[0037] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the drawings.

[0038] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a circuit board module provided by an embodiment of the present application. The circuit board module 000 may include: a circuit board body 100, and a shrapnel assembly 200 connected to the circuit board body 100.

[0039] The shrapnel assembly 200 in the circuit board module 000 may include: a base 201 fixed on the circuit board body 100, a transmission part 202 movably connected to the base 201, and a first shrapnel 203 and a second shrapnel 204 connected to the transmission part 202.

[0040] Among them, after the first elastic piece 203 in the elastic piece assembly 200 abuts against the first contact A in the functional component, the transmission part 202 in the elastic piece assembly 200 can be used to drive the second elastic piece 204 to abut against the second contact B in the functional component, and the acting force exerted by the first elastic piece 203 on the first contact A in the functional component and the acting force exerted by the second elastic piece 204 on the second contact B in the functional component can be in opposite directions.

[0041] In the embodiment of the present application, the circuit board module 000 can be integrated in a terminal device (not shown in the figure). The functional component in the terminal device can be electrically connected to the circuit board body 100 through the elastic piece assembly 200 in the circuit board module 000. The first elastic piece 203 in the elastic piece assembly 200 can abut against the first contact A in the functional component, and the transmission part 202 can be used to drive the second elastic piece 204 to abut against the second contact B in the functional component. The first elastic piece 203 can exert an acting force F1 on the first contact A in the functional component, and the second elastic piece 204 can exert an acting force F2 on the second contact B in the functional component, and the directions of these two acting forces are opposite. That is, the direction of the reaction force F3 exerted by the first contact A in the functional component on the first elastic piece 203 is opposite to the direction of the reaction force F4 exerted by the second contact B in the functional component on the second elastic piece 204. In this way, after the two elastic pieces abut against the two contacts in the functional component, elastic forces in two directions can be realized, and the two elastic pieces are self-locked with each other, effectively ensuring the connection stability between the functional component and the circuit board body. In addition, through the connection of two elastic pieces in two directions, even if a single direction of one elastic piece fails, there is still another elastic piece that effectively abuts against the functional component in the other direction.

[0042] Exemplarily, the circuit board body 100 can be a printed circuit board (English: Printed Circuit Board; abbreviation: PCB).

[0043] In summary, the embodiment of the present application provides a circuit board module, which may include: a circuit board body, and a shrapnel component connected to the circuit board body. The circuit board module can be integrated in a terminal device, and the functional components in the terminal device can be electrically connected to the circuit board body through the shrapnel component in the circuit board module. Moreover, the first shrapnel in the shrapnel component can abut against the first contact in the functional component, and the transmission part can be used to drive the second shrapnel to abut against the second contact in the functional component. The first shrapnel can apply a force to the first contact in the functional component, and the second shrapnel can apply a force to the second contact in the functional component, and the directions of these two forces are opposite. That is, the direction of the reaction force applied by the first contact in the functional component to the first shrapnel is opposite to the direction of the reaction force applied by the second contact in the functional component to the second shrapnel. In this way, after the two shrapnels abut against the two contacts in the functional component, two-direction elastic forces can be realized, and the two shrapnels are self-locked with each other, effectively ensuring the connection stability between the functional component and the circuit board body. In addition, through the connection of the two shrapnels in two directions, even if one shrapnel fails in a single direction, there is still another shrapnel that effectively abuts against the functional component in the other direction.

[0044] Optionally, please refer to Figure 2 and Figure 3 , Figure 2 which is a schematic structural diagram of another circuit board module provided by the embodiment of the present application. Figure 3 is Figure 2An exploded schematic diagram of a circuit board module is shown. The transmission part 202 in the shrapnel assembly 200 may include: a slider 202a, a rotating member 202b and a connecting rod component 202c. The slider 202a in the transmission part 202 may be fixedly connected to the first shrapnel 203, and may be slidably connected to the base 201. The first end of the rotating member 202b in the transmission part 202 may be fixedly connected to the second shrapnel 204, and the portion of the rotating member 202b located between the first end and the second end of the rotating member 202b may be rotatably connected to the base 201. The connecting rod component 202c in the transmission part 202 may be rotatably connected to the slider 202a, the second end of the rotating member 202b and the base 201, respectively. Among them, after the first elastic sheet 203 abuts against the first contact A in the functional component, the slider 202a can be used to slide in a direction away from the first contact A of the functional component, so as to drive the second elastic sheet 204 to rotate in a direction toward the second contact B through the connecting rod component 202c and the rotating member 202b. For example, during the assembly of the circuit board module 000 and the functional component in the terminal device, after the first elastic sheet 203 abuts against the first contact A in the functional component, the slider 202a fixedly connected to the first elastic sheet 203 can move in a direction away from the first contact A under the action of an external force, so as to drive the second elastic sheet 204 to rotate in a direction toward the second contact B through the connecting rod component 202c and the rotating member 202b, so that the second elastic sheet 204 can abut against the second contact B in the functional component through the connecting rod component 202c and the rotating member 202b.

[0045] In the embodiments of the present application, Figure 2 and Figure 3 As shown, the rotating member 202b in the transmission part 202 may include: a first rod body C1 and a second rod body C2 connected to each other, the length direction of the first rod body C1 and the length direction of the second rod body C2 may intersect, and the portion where the first rod body C1 and the second rod body C2 are connected may be rotatably connected to the base 201. The end of the first rod body C1 away from the second rod body C2 may be fixedly connected to the second elastic sheet 204, and the end of the second rod body C2 away from the first rod body C1 may be rotatably connected to the connecting rod component 202c. In this case, the slider 202a can drive the connecting rod component 202c to rotate during the sliding process along the base 201, and then drive the second rod body C2 and the first rod body C1 to rotate in the same direction relative to the base 201 during the rotation of the connecting rod component 202c, that is, the second elastic sheet 204 is driven to rotate toward the second contact point B in the functional component through the first rod body C1, and finally the second elastic sheet 204 is abutted against the second contact point B in the functional component.

[0046] Optional, please refer to Figure 4 and Figure 5 ,Figure 4 is a front view of a circuit board module provided in an embodiment of the present application, Figure 5 yes Figure 4 The exploded schematic diagram of the circuit board module is shown. The connecting rod component 202c in the transmission part 202 may include: a third rod body D1 and a transfer connecting rod group D2, the first end of the third rod body D1 may be rotatably connected to an end of the second rod body C2 away from the first rod body C1, the second end of the third rod body D1 may be rotatably connected to the transfer connecting rod group D2, and the two ends of the transfer connecting rod group D2 may be rotatably connected to the slider 202a and the base 201 respectively. In the process that the slider 202a slides in the direction away from the first contact point A, the transfer connecting rod group D2 drives the second end of the third rod body D1 to rotate in the direction away from the first contact point A. In this case, when the slider 202a slides in a direction away from the first contact A in the functional component, the rotation of the transfer link assembly D2 can drive the second end of the third rod D1 to rotate in a direction away from the first contact A, and then the third rod D1 drives the second rod C2 and the first rod C1 to rotate, so that the second spring piece 204 rotates in a direction toward the second contact B in the functional component.

[0047] In the embodiments of the present application, Figure 4 , Figure 5 and Figure 6 As shown, the transfer connecting rod group D2 in the transmission part 202 may include: a first sub-rod body D21 and a second sub-rod body D22 arranged in a cross pattern, one end of the first sub-rod body D21 and one end of the second sub-rod body D22 may be rotatably connected, and both may be rotatably connected to an end of the third rod body D1 away from the second rod body C2. The end of the first sub-rod body D21 away from the second sub-rod body D22 may be rotatably connected to the slider 202a, and the end of the second sub-rod body D22 away from the first sub-rod body D21 may be rotatably connected to the base 201. In this case, when the slider 202a slides relative to the base 201, when the first sub-rod body D21 rotates, the second sub-rod body D22 and the third rod body D1 may both rotate, and the second sub-rod body D22 may limit the rotation trajectory of the third rod body D1, so as to ensure that the third rod body D1 can stably drive the rotating member 202b to rotate toward the direction of the second contact point B in the functional component. In the present application, in the direction f1 perpendicular to the sliding direction of the slider 202a relative to the base 201, the first elastic sheet 203 and the second elastic sheet 204 can be respectively distributed on two opposite sides of the base 201, and the third rod body D1 can be located between the rotating member 202b and the transfer connecting rod group D2. In the direction f1 parallel to the sliding direction of the slider 202a relative to the base 201, the first rod body C1 can be located between the first contact point A in the functional component and the second contact point B in the functional component.

[0048] In the embodiments of the present application, Figure 3As shown, the base 201 may have a strip-shaped guide rail 201a, and the slider 202a may have a chute a1 that cooperates with and slides along the strip-shaped guide rail 201a. At least a part of the strip-shaped guide rail 201a may be located within the chute a1. In this case, by providing the strip-shaped guide rail 201a in the base 201 and the chute a1 that cooperates with and slides along the strip-shaped guide rail 201a in the slider 202a, the strip-shaped guide rail 201a can guide the sliding of the slider 202a, ensuring that the component composed of the first elastic piece 203 and the slider 202a can slide stably relative to the base 201 during the assembly of the terminal device.

[0049] Optionally, as Figure 3 shown, the number of the second rod bodies C2 in the rotating member 202b may be two. Both of the two second rod bodies C2 may be connected to the first rod body C1 and may be oppositely arranged; the number of the third rod bodies D1 in the link member 202c may be two. The two third rod bodies D1 may be oppositely arranged, and the number of the transfer link groups D2 in the link member 202c may be two. The two transfer link groups D2 may be oppositely arranged. Among them, one end of a second rod body C2 facing away from the first rod body C1 is rotatably connected to the first end of a third rod body D1, and the second end of the third rod body D1 is rotatably connected to a transfer link group D2. One end of the other second rod body C2 facing away from the first rod body C1 may be rotatably connected to the first end of the other third rod body D1, and the second end of the third rod body D1 may be rotatably connected to the other transfer link group D2. In this application, as Figure 2 and Figure 3 shown, the base 201 may have a hollowed-out groove a2. The part where the first rod body C1 and the second rod body C2 are connected may extend into the hollowed-out groove a2 of the base 201 and be rotatably connected to the base 201. In this case, the overall thickness of the circuit board module 000 can be effectively reduced by providing the hollowed-out groove a2.

[0050] In summary, the embodiment of the present application provides a circuit board module, which may include: a circuit board body, and a shrapnel component connected to the circuit board body. The circuit board module may be integrated in a terminal device, and the functional components in the terminal device may be electrically connected to the circuit board body through the shrapnel component in the circuit board module. Moreover, the first shrapnel in the shrapnel component may be in contact with the first contact in the functional component, and the transmission part may be used to drive the second shrapnel to be in contact with the second contact in the functional component. The first shrapnel can apply a force to the first contact in the functional component, and the second shrapnel can apply a force to the second contact in the functional component, and the directions of these two forces are opposite. That is, the direction of the force applied by the first contact in the functional component to the first shrapnel is opposite to the direction of the force applied by the second contact in the functional component to the second shrapnel. In this way, after the two shrapnels are in contact with the two contacts in the functional component, elastic forces in two directions can be realized, and the two shrapnels are self-locked with each other, effectively ensuring the connection stability between the functional component and the circuit board body. In addition, through the connection of the two shrapnels in two directions, even if one shrapnel fails in a single direction, there is still another shrapnel in contact with the functional component effectively in the other direction.

[0051] The embodiment of the present application also provides a terminal device, which may be a product or component such as a smart phone, a tablet computer, a laptop computer, a camera, etc. Please refer to Figure 6 , Figure 6 FIG. is a schematic structural diagram of a terminal device provided by the embodiment of the present application.

The circuit board module 000 may be any of the circuit board modules given above.

[0052] In summary, the embodiment of the present application provides a terminal device, which may include: a functional component and a circuit board module. The functional component in the terminal device can be electrically connected to the circuit board body through the elastic sheet component in the circuit board module. And the first elastic sheet in the elastic sheet component can abut against the first contact in the functional component, and the transmission part can be used to drive the second elastic sheet to abut against the second contact in the functional component. The first elastic sheet can apply a force to the first contact in the functional component, and the second elastic sheet can apply a force to the second contact in the functional component, and the directions of these two forces are opposite. That is, the direction of the force applied by the first contact in the functional component to the first elastic sheet is opposite to the direction of the force applied by the second contact in the functional component to the second elastic sheet. In this way, after the two elastic sheets abut against the two contacts in the functional component, elastic forces in two directions can be realized, and the two elastic sheets are self-locked with each other, effectively ensuring the connection stability between the functional component and the circuit board body. In addition, through the connection of the two elastic sheets in two directions, even if one elastic sheet fails in a single direction, there is still another elastic sheet that effectively abuts against the functional component in the other direction.

[0053] Optionally, please refer to Figure 7 , Figure 7 which is a schematic structural diagram of another terminal device provided by the embodiment of the present application. The terminal device 00 may further include: a housing 002, which may have an installation space b1 and a bearing groove b2 communicating with the installation space b1. The functional component 001 may be connected to the housing 002, and the circuit board module 000 may be located in the installation space b1. Among them, the first contact A in the functional component 001 may be fixed in the installation space b1 of the housing 002, and the second contact B in the functional component 001 may be fixed in the bearing groove b2 of the housing 002. Exemplarily, when the terminal device is a smart phone, the housing may be the middle frame in the smart phone.

Among them, the first contact A in the functional component 001 may be fixed on the bottom plate E2 of the housing 002, and the second contact B in the functional component 001 may be fixed on the groove surface opposite to the bottom plate E2 in the bearing groove b2.

[0055] In this way, please refer to Figure 8 , Figure 8It is an assembly schematic diagram of a circuit board module and a functional component provided by an embodiment of the present application. During the assembly process of the circuit board module 000 and the housing 002, the first elastic piece 203 in the elastic piece assembly 200 first contacts the first contact A in the functional component 001. As the distance between the elastic piece assembly 200 and the bottom plate E2 shortens, the slider 202a fixedly connected to the first elastic piece 203 can slide relative to the base 201, and further enables the transfer link group D2 rotatably connected to the slider 202a to drive the third rod body D1 to rotate. During the rotation of the third rod body D1, it can drive the rotating member 202b to rotate, and finally drive the second elastic piece 204 to rotate towards the direction of the second contact B of the functional component 001, so as to realize the abutment of the second elastic piece 204 and the second contact B of the functional component 001.
